I got MS ps2 natural keyboard/A4tech 4D ps2 mouse and DFI AD-72SN (via kt266) motherboard. I have tryed new a4tech drivers for XP, old drivers too, still no efect, just for info - once i tryed to update mouse driver back to ms standart ps2 mouse it sayed something like "Warning! This device drivers using same port as keyboard device drivers, if you continue the drivers(setings?) will be replaced."
ps: sorry for me poor english
